Hi fstevenj,

You will get a huge divergence of opinion on this topic and all will be correct to their own lights, it's you "who pays your money and takes ya pick".

I have used Dubro fuel valves for many years without a problem. Many will tell you horror stories of unreliability, loss of valve connector etc, etc but I like them.

To mount the valve I use a small piece of angle alloy behind the cowl so the valve mounts to the engine box and the hole in the cowl is just large enough to allow the fitting to reach the valve.

Cheers,

Colin
